OBVILLE T. SMITH, OF BROOKLYN, NEW YORK.

COLLAR OR SLEEVEBUTTON.

fiPECIFICATION forming part of Letters Patent No. 316,194, dated April 21, 1885.

Application filed January 12, 1885. (No model.)

To all whom it may concern:

Be it known that I, ORVILLE T. SMITH, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Collar and Sleeve Buttons, of which the following is a specification.

My invention relates to those collar and sleeve buttons in which the post is hollow or tubular and made from a continuous piece of metal, without seam or joint, and more particularly to those buttons in which the post has the back plate or shoe formed integral with it.

The object of my invention is to enable the heads of buttons of this class to be made of a fine grade of gold, and the post and back plate, which constitute the principal part by weight, to be made of a less fine grade of gold, whereby I produce a button which is equal in appearance to, and much less expensive than, a button having the head and post integral from one continuous piece of metal.

The invention consists in novel combinations of parts, hereinafter described, whereby the desired result is attained.

In the accompanying drawings, Figure 1 is a sectional view, on an enlarged scale, of a button embodying my invention. Fig. 2 represents that part which is to form the head, and Fig. 3 is a sectional view of the post and back plate ready to receive the head.

Similar letters of reference designate corresponding parts in all the figures.

A designates the hollow post, and B the back-plate, of the button. The post A is made of one piece of metal without seam or joint, and, as here represented, the post and the back-plate B are formed integral from a single piece of sheet metal, and compose the principal part, by weight, of the button. The backplate B has its outer edge rolled or turned inward, as shown at b, to give ita neat finish and thick edge, and there is formed at the upper or outer end of the post A an outwardlyextending flange, {(0, at the margin or border of which is an upturned rim, a

The head 0 consists of a cap of inverted cup shape, which is made slightly larger in diameter than the rim w and is slipped over the same, as shown in Fig. 1. The edge of the head or cap is turned inward, as shown at so as to slightly underlie the rounded corner at the junction of the flange a and rim 66*, and

thereby secure the head to the post A.- The worn, and hence this is the part which it is most desirable should be highly finished. The post and back plate make up almost the whole weight of the button, and a high finish thereof is not so necessary. A fine or high grade of gold is susceptible of a fine finish, and by making. the button as described I may employ a fine grade of gold for the head or smaller part, without the necessity of making the whole button of a fine grade of gold.

I am aware that it is not new to make abutton with its head-post and back-plate all integral with each other from one continuous piece of metal without seam or joint; and I am also.

aware that it is not new to make a button with a flanged hollow post formed of a piece of sheet metal bent into shape and .having a seam -lengthwise of the post, which seam must be soldered, and having a head made of a separate piece and secured to the flanged end of thepost.

I make no claim to a button of either of the constructions above referred to, but desire to limit my invention to a button having a tubular post made in one piece without seam or joint, and provided at the outer end with an integral flange, a, and upturned rim a and a cup-shaped head, 0, made separate from and secured to the flanged end of the post in the manner herein described. It is' very desirable that the button shall be made with- I rim, (0*, both formed integral with the shank 10 out any soldering, as such operation weakens f or post, and a cup-shaped head, 0, fitting outthe metal by annealing it. side the flange and rim a (timid having its edge What I claim as my invention, and desire turnedinward under the flange a, substantially 5 to secure by Letters Patent, is as and for the purpose herein described.

The collar or sleeve button herein described, ORVILLE T. SMITH.
